Its precision can be imagined only when one realizes that the spark must jump the spark plug gap at that precise instant when the piston is close to the top of its cylinder,with the trapped explosive air-fuel mixture compressed and ready to be ignited.
To realize enormity of this exacting task,imagine an 8-cylinder engine operating at 4000 rpm,a rather high speed.in one minutemthe ignition system will have to furnish and deliver 16000sparks,each one sent to the proper plug and timed to the split fraction of a second when the piston is close to the end of its compression stroke.This is almost 300 sparks each second.
